This paper reviews the technology and biotechnology to remove heavy metals (such as
copper, arsenic, lead and zinc) and cyanide from contaminated wastewater. The paper …

The test and use of natural materials as adsorbents for the removal of various pollutants
such as heavy metals from industrial wastewater is under constant development …

The current study deals with the interaction of toxic metals with soils by conducting a series
of leaching tests on four kaolinitic soils procured from locations with varying pollution levels …

The soils in hazardous waste sites contain heavy metals which would leach into
groundwater by various biotic and abiotic processes and eventually pose a threat to human …

The relative performance of two soils as a sustainable material to attenuate the transport of
heavy metal ions, cadmium (Cd 2+) and nickel (Ni 2+), from aqueous solutions has been …

In this study, locally available semi-arid soils (Al-Ghat and Al-Qatif) having different chemical
and mineralogical characteristics are considered as barrier materials, and their response to …

In recent years the uses of waste as a raw material for producting porous carbon have been
widely employed in the purification of water and wastewater. The application of these …

In this study soils were sampled from three different locations which were at high risk for
contamination having different categories of hazardous wastes such as steel plant …

Remediation of brown fields is a challenge and this paper aimed at quantifying the extent of
heavy metal pollution in contaminated soils and used a Nano based amendment to …

Chromium (VI) and copper (II) are the most significant industrial effluent whose direct
discharge into nearby waterways creates water pollution. Wastewater containing Cr (VI) is …
